If a colony has _lost its queen_, and this loss cannot be supplied, it must, as a matter of course, fall a sacrifice to the bee-moth: and I do not hesitate to assert that by far the larger proportion of colonies which are destroyed by it, are destroyed under precisely such circumstances!

If the sides of the hive are of glass, and the corners are run with a melted mixture, three parts rosin, and one part bees-wax, the bees will waste but little time in gathering propolis, and the bee-moth will find but little chance for laying her eggs, even if she should succeed in entering the hive.

In the common hives, but little can be done to dislodge the bee-moth, when once it has gained the mastery of the bees; whereas in mine, it can be most effectually rooted out when it has made a lodgment.

If this operation is judiciously performed, the bees will be powerful in numbers, long before the weather is warm enough to develop the bee-moth, and they will thus be most effectually protected from the hateful pest.
